Abstract

An oxidation catalyst for the oxidation of styrene to benzaldehyde and acetophenone, the oxidation catalyst comprising: a porous support; and an active phase comprising an oxygen activation metal comprising cobalt (Co), manganese (Mn), iron (Fe), molybdenum (Mo), or a combination thereof. A method of forming the oxidation catalyst, a method of forming an oxidation product comprising benzaldehyde and acetophenone by contacting the oxidation catalyst with styrene and air in an oxidation reactor, and a system and method for reducing the fouling in a process for the production of styrene by introducing an additive stream comprising at least a portion of the oxidation product into a stream comprising styrene and byproduct divinyl benzene (DVB) are also disclosed.
